<p>This is an example of how to add an ArcIMS layer to an OpenLayers map.</p>
<p>Following the ArcXML convention to create a thematic (or chloropleth) map,
a layer definition is created with a query and a renderer to select portions
of the map data, and change their representation in the generated map tiles.</p>
